PACKING-I'PAZD-FOEMING MACHINE.

To all whom it may concern.-

Be it known that I, ALBERT O. PETERSON, a citizen of the United States, and resident of St. Louis and State of Missouri, have invented certain new and useful Improvements in Packing-Pad-Forming Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

The object of my invention is to provide a simple and effective feeding-mechanism for disintegrating and feeding the filler of pad-forming machines, the construction and arrangement being such that the elastic filling is thoroughly disintegrated by a novel feed-mechanism and deposited in an even layer of predetermined width and thickness upon a paper-wrapper strip, which strip is thereafter folded about the filling and sealed in the usual manner employed in pad-forming machines of the character to which my invention relates.

The invention therefore consists in what is herein described with reference to the accompanying drawings and subsequently claimed.

Figure 1 is a longitudinal sectional view of the rear or feeding-end of a pad-forming machine embodying the features of my invention, parts being broken away and parts in section to more clearly illustrate structural features; Fig. 2,'a plan view of the same with parts broken away and parts in section to better illustrate the invention, and Fig. 3, a detail cross-section, as indicated by line 66 of Fig. 1, showing adjustable wings for controlling the width of filler delivered to the wrapper.

Referring by numerals to the drawings, 1 indicates a housing fitted upon a suitable frame structure, and 2 a portion of an end less lagged delivering apron, which is driven and supported by a roller 8 mounted within the housing. Above the roller 3 is located a pin-studded roller 4, which roller is in spurgear connection with the roller 3, the gearing being so proportioned as to impart the same peripheral speed to the pin-studded roller as that of the delivery apron. The filling material is carried by the apron under the pin-studded roller 4c and from thence is die livered to a pin-studded drum 5, from which drum the filler is stripped by a similar pinstudded drum 6, arranged to travel at a greater speed than the former. The filling Specification of Letters latent.

material caught by drum 6 is passed under a small roller 7 and caught by spurs 8 of a picker-cylinder 9, which cylinder is rotated at a proportionately high-speed, by a belt 10. The speed of rotation of the cylinder 9 is such that the filling material is thrown off therefrom by centrifugal force and deposed upon an endless conveyor-apron 11, which apron is mounted upon a rear idle roller and forward driven roller 12, the latter being mounted in suitable bearingblocks carried by one of a pair of sills 13, which extend from the rear housed portion of the frame.

Extending from a cross-beam 14: above the pin-studded roller 41, are a series of spring-tangs 15, one only of which is shown, the free-ends of which tangs terminate over the drum 5 at such distance from its periphery sufiicient to permit a normal thick ness of filling material to pass therebetween, the drum and spring tangs together constituting a throat for the reception of said material. Just above the free-ends of the tangs 15 is located toothed stripper-drum 16, the ends of its teeth being normally disposed above the line of said tangs, and in such relation thereto that should the normal thickness of filler material be fed, the stripper drum will have no effect thereon. If an increased thickness passes under the tangs however, the same will lift and expose the points of the stripper-drum teeth in such manner that said teeth will catch the surplus material and deliver itinto the mouth of a funnel 17, it being understood that said stripper-drum 16 is rotated at a high-speed, by means of a suitable driving-belt, as shown.

Owing to the speed of the stripper-drum, the material is freed from the teeth thereof and forced through the funnel 17, by means of a draft created by the several rotating drums and cylinder within the housing 1, the said surplus filling being deposited back upon the pile or stack of material rearward of the apron. Thus it will be seen that a uniform feed of filling-material is automatically maintained without necessitating the employment of variable speed clutches in order to check the flow of said filling an expedient which is usually necessary in machines of the class to which my invention pertains. The drums 5 and 6 are driven by means of a belt-and-pulley connection from a counter-shaft 18, the apron-roller 3 being also driven in a similar manner from the counter-shaft. The small roller 7 located adjacent to drum 6, is driven at the same peripheral-speed as the latter, by means of a pinion, which pinion is in gear-connection with. the shaft of said drum 6, as indicated by dotted lines in Fig. 1. The countershatt 18 in turn is back-geared to a shaft 19, which is in belt-and-pulley connection with a similar shaft 20, the latter being driven by bevel-gears from a longitudinal power-shaft 21, all of which system of gearing consti tutes no part of the invention, and may be varied, to form, in accordance with the speed required for the different rotating parts.

Nhen the filling-material is delivered upon the conveyer-apron 11, it is caught and defiected thereon between a pair of wings 22, which are hinged to the side walls of the housing, the wings being provided with slotted keepers 23 that are in pivotalconnection therewith and extend through apertures in said housing side-walls, at which point the keepers are secured by means of set-bolts 24:. By this construction the wings may be relatively set so that the filling material falling therebetween can be regulated to any width oi layer desired. The driven roller 12 of the carrying-apron is in gearconnection with a spring-controlled compression-roller located above the same, and between which rollers the filling-material passes to a tray 26. This tray being formed with converging side flanges, which serve to further contract said layer of filling as it passes to another set of spring-controlled compression-rollers 27, 27, respectively.

Suspended in suitable hangers carried by the machine-frame is a roll of paper 28, which paper constitutes the w 'apper-portion of the pads and is located under the compression-rollers 2'? 27. The paper-wrapper passes over an idle-roller adjacent the before mentioned compression-rollers, and from thence over a table 30 to tl e forward or cutting-end of the machine, (not shown) at which end of the machine the wrapper is folded, sealed and thereafter cut in the usual manner. A glue-pot 32 as shown in Fig. 2 of the drawings, is mounted upon the frame, having its nozzle so disposed as to feed glue to one edge of the wrapper, whereby said wrapper is sealed after being folded as previously stated.

I claim:

1. A feed-mechanism :t'or pad-forming machines, comprising a delivery-apron, a pinstudded. drum disposed at the delivery-end of the apron, a series of spring-tangs above the drum, which tangs together with said drum constitute a receiving-throat for filling material, a tooth stripper drum above the free-ends of the spring tangs, and a discharge-funnel having its mouth adjacentto the strippendrum.

2. A feed-mechanism for pad-forming machines, a pin-studded roller above the apron, a pin-studded drum disposed at the delivery end of said apron, a series of spring tangs above the drum, the spring tangs and tongue constituting a receiving-throat for filling material, a second pin-studded drum arranged to operate in-eonjunction with the first named drum, a smooth-faced feed-roller above the second pin-studded drum, a pickercylinder provided with spurs adapted to act in conjunction with the pins of said second drum, a toothed stripper drum located above the tree-ends of the spring-tangs, and a discharge-tunnel having its mouth adjacent to the stripper-drum.

3. A feed-mechanism for pad-forming machines, having a frame and ahoused receiving-end, filling material delivery means in connection with the housed receiving-end, pin studded drums revolubly mounted in the housed receiving-end, a pickei cylinder mounted therein arranged to operate in conjunction with the pin-studded drums, an air-tunnel in connection with said housed recei'viiigend, and means for delivering surplus filling material into the funnel.

i. A feed-mechanism for pad-forming machines having filling material delivery means, mechanism in connection with the delivery means for controlling the filling material supply, and other means for returning surplus filling material back to the source of supply.

in testimony that I claim the foregoing I have hereunto set my hand at city of St. Louis and State of Missouri in the presence of two witnesses.
